Ali Clara and Shane raise money for new books for the school library all Ellie rays 20% more than Clara and $58 more than Shan C
Vikki [24]

Answer:

a. $435

b. 33.33%

Step-by-step explanation:

P.S - The exact question is -

Let Clara raised money = x

As given,

Ali raised 20% more than Clara

⇒Ali raised money =  x + \frac{20}{100}x = x + \frac{1}{5} x = \frac{6}{5}x

Also given,

Clara raised \frac{1}{4} times more than Shan

Clara raised money = Shan raise money + \frac{1}{4} times shan raired money

⇒Clara raised money = \frac{5}{4}  Shan raised money

⇒Shan raised money =  \frac{4}{5} times Clara

⇒Shan raised money = \frac{4}{5} x

As given,

Ali raised $58 more than shan

⇒\frac{6}{5}x = \frac{4}{5}x + 58

⇒\frac{6}{5}x -\frac{4}{5} x = 58

⇒\frac{2}{5}x = 58

⇒x = (29)(5) = $145

∴ we get

Clara raised money = x = $145

Ali raised money = \frac{6}{5}x = $174

Shan raised money =\frac{4}{5} x  = $116

a.)

Total raised money = $145 + 174 + 116 = $435

b.)

Percentage of money Clara raised = \frac{145}{435}×100% = \frac{1}{3}×100% = 33.33%

The reciprocal of a fraction less than 1 is always a fraction greater than 1.why is this?
Rama09 [41]
First of all, you know that a fraction is smaller than 1 if the top number is smaller than the bottom. It works both ways, meaning that if the top number is larger than the bottom number, the fraction is greater than 1.

So, for example, a fraction less than 1 can be expressed as
(x-1)/x
because the top number is smaller than the bottom number.

The reciprocal can be found by flipping the top and the bottom, so the reciprocal is
x/(x-1)

x is always greater than x-1, so in the reciprocal, the top number will be larger than the bottom number. That means it will always be greater than 1.

Hope this helps!
(Sorry if this is confusing)
